You can use a child or adult counter service credit here!
We got ham & cheese crossaints and various pastries as well as a large drink all for a counter service credit -- adult or child.
We love the Napoleons and the Ham & Cheese Crossaints best (the ham and cheese crossaints are warm and the cheese is melted and so yummy with the flaky buttery crossaint!), but we have not tried anything that we didn't like. My son loved the fruit tarts.
I can't wait to go back -- it is a must on every trip to Epcot! Great to take back for later at the hotel too.
